1. To make a hat, take the back of your t- shirt and cut it out. Fold it in half and make sure it fits loosely around your head.
2. Take 1 side sew it and pull it together.... Do the same with the other side.
That's what it should look like ^
Flip it back so it is no longer inside out. BTW this is more of a fashion hat.
